IC1805 Narrowband sent on September 01, 2015 (21:49) by Franco Sgueglia. 53 comments, 5444 views.  [editors pick]

Dopo 8 anni di fermo sono tornato a scattare. Complice la nascita del figlio di un mio caro amico che gentilmente mi ha concesso di utilizzare il suo setup . Cosa che ho fatto in questi giorni dal terrazzo di casa, a metà tra Lecco e Milano . Cielo inquinato e umido , luna piena. Come potevo provare a scrollarmi di dosso la ruggine di 8 anni di fermo? Fare una prima prova in NarrowBanding . Non è andato tutto per il verso giusto . Ma il risultato mi ha comunque soddisfatto . Sono al mio primo tentativo di elaborazione di questo tipo di foto . Siate indulgenti . IC1805 Di seguito i dati : Telescopio SW ED 80 su Skywatcher AZ Eq6, camera di ripresa ATIK 383mono , telescopio guida 80/400 acro . Dati di ripresa: Ha 3x 60 min , SII 17 x 30 min, OIII 13 x 30 min . Molte pose purtroppo le ho dovute scartare per passaggi di nuvole. No flat, no dark.

Can you explain in simple terms, if you can, to a mere mortal what is the Narrow Banding? Thank you!

Shooting narrowband .. H alpha,
Third oxygen OIII, and baseband sulfur think ... Nice job .. :)

I do not remember seeing recently a Heart Nebula so detailed, largely in H-alpha OIII SII how you shoot you ... I see that the 8-year absence you have not removed the nail polish, even if you had to discard the frames and not to apply the offsets you've done is a remarkable work, largely in processing. This shooting technique is starting to like it more and more ;-) Beautiful. Bravissimo Franco.

A greeting
Gp

Thank you all !!!!!
Hello Giampaolo (gp70) I also remember very well
tea . I think we met on the first version of Astrofili.org, about ten years ago.
I'm glad to meet you again.

for Pasotteo, the response of Canopo70 is correct. Shooting
narrowband (narrowband) made these filters also called "interference"
highlights emissions details of subjects (almost always) nebular:

Ha: Hydrogen Ionized
Oiii: Oxygen
SII: Sulfur ionized

Edit:
each of these filters is centered on the wavelength of emission of the atoms listed above:
It has around 658 nm, around 672nm SII, OIII around 500nm.
Another important feature of the filters and 'bandwidth. They can be narrow or more
large (generally from 3nm to 12 nm). This means that, centered above the band,
for example, if we have a 658nm filter to 6 nm gonna go all the light including
between the wavelengths ranging between 655nm (658-3) and 661nm (658 + 3) and so on.
Most nebulae have strong emission in the HA (Hydrogen).
So that it is "easier" to capture the detail and contrast in this band. The other two are a bit 'more
ostiche.


filming respective realized with these filters are replaced, in phase combine the colors, to
normal RGB. There are various methods, one of which is the palette of Hubble made
for filming made with HST (Hubble space telescope). The latter is what I tried
to apply to the processing of the image you see.

Breathtaking ... especially considering that it was created by an observatory with equipment costs "astronomical" ... Very nice.
